The United States have adopted competitive and even conflictive trade policies to redefine and rewrite the global political economy in the post globalization era. The prime movers of removing trade barriers and expanding trade concession, have adopted a restrictive theory of trade after terrorist attacks of 9/11, with a gradual shift from an easy international trade environment to a selective preferential trade relations with like- minded countries. New measures and technologies were developed to track movement of different goods. Logistics and international shipping industries were negatively affected due to national restrictive policies. The international financial crisis and Covid-19 were additional factors to push developed countries to adopt protective trade policies to neutralize the negative impact of the crisis in the absence of financial resources. Former trade partners were considered competitors and those with different trade theories or interests became adversaries. US trade disputes and conflicts surged in XXI century and international dispute settlement mechanisms were challenged by US foreign policy to obtain concessions. This article is meant to respond to the question that “What is the US practice in international trade in the post-globalization era and what would be the implications for the developing countries and global business environment”? The hypothesis is that “US trade policy and practice in the twenty first century has been affected by global geopolitics and geo- economics, where emerging poles of power are meticulously considered and long-term strategies are adopted. In this context; trade disputes, wars and sanction diplomacy might happen either for trade inequality concerns, optimal tariff theory, or politically painted economic objectives”. A qualitative analytical methodology is used to study roots and causes of re-globalization wars and to analyze consequences of antagonistic approaches for the multilateral trading system. A new liberal theoretical framework is used to analyze post- globalizations US trade practices.
